You need to go to ccf's and set the display screen to high spec.

I would recomend that before you do anything you download the guide from the Gap website it tells you what to do and also what to do if it goes wrong.
I would also save your current settings befire changing anything.

When you make changes some things can take a very long time so you need to make sure you have an alternative power supply to stop the battery going flat.
Setting up the 4x4 screen is a good one to start with as it takes seconds, be warned the first time you change things it can be quite scary as all the electronics will suddenly go dead for what seems like ages. its important that you dont do anything just leave it and it will suddenly come back to life, if you look on the app you will see a count down that will tell you when it will be finished.
